British actress Parminder Nagra and her husband James Stenson have welcomed their first child together, a little boy they have named Kai David Singh Stenson.

The ER actress, 33, gave birth Kai on May 19. "Mother, daddy and baby are all doing great," her representative confirmed to US mag People.

Parminder's pregnancy also played out on the small screen after producers of the medical drama decided to include it in some final episodes. "We were trying to juggle how that was going to work because she was starting to show," the programme's executive producer explained.

"There was a tremendous feeling of, 'Oh, there's this one (story) that we haven't done,' so it's actually very exciting."

Leicester-born Parminder and her photographer spouse married on January 17 after seven years together
